2. Consider the strategic-form game below:
P2
L
R
A
0, 10
8, 15
P1
8, 8
0, 5
C
1, 3
6, 12
2.1. Let m, be a mixed strategy for P1 (m,(A), m, (B)) = (p, 1 – p). Note that m, (C) = 0.
Furthermore, assume P2 is playing a mixed strategy with (m2 (L),m2 (R)) = (q, 1 – q). Write
an expression for u1(m1,m2) in terms of p and q.
2.2. Write an expression for u1 (C,m-¡), the expected utility to P1 playing C when P2 is playing
a mixed strategy.
2.3. Notice that neither pure stra
mixed strategies that obtain a strictly higher payoff for P1 than C when P2 plays L and when
P2 plays R.
A nor B strictly dominates C. Show that there are A-B-
